We all live in surrounding which includes living things and natural forces. Living things not only live in the surrounding but interact with it as well. They affect the surrounding and are affected by the surrounding. The places we live in consist of air, water, land, plants, animals and the micro- organisms; they all are part of environment. We depend upon our environment to fulfill our various needs such as oxygen, food and shelter etc. We must keep our surroundings neat and clean to live healthy life.
To stay healthy we need a clean environment. For a healthy living, two things are required, sanitation and hygiene. Hygiene means practice that we follow to stay healthy and clean. Sanitation means measure we adopt for improving and protecting health and well-being of ourselves.
Every household generates waste or garbage. We should not throw waste or garbage anywhere. Dirty surroundings help in the growth of germs that cause diseases, like cholera, typhoid, dengue etc. Dirty and stagnant water is the breeding ground of mosquitoes. Mosquitoes cause malaria.
Proper disposal of waste is necessary to keep our environment clean. Waste water from our houses should go through proper drainage system and should be treated before dumping it into water bodies such as sea or ocean. In metropolitan cities, there are huge underground pipelines that are connected to the main sewage line which passes through the treatment plant where waste water get treated by various method and then finally get disposed of.
Solid waste from houses such as vegetable peels, waste paper, plastic bags etc. should be thrown in covered garbage bins. Throwing of these solid wastes out of houses in open area cause piling of waste which attracts flies and germs and spread diseases. Open dumping of waste may cause land, air and water pollution.
Waste material such as fruits and vegetable peels, decomposes easily. These are called biodegradable materials. Biodegradable material can be disposed of making compost pits. Solid waste kept in pit turn into manure that can be used for crops. Many things like plastic, glasses etc. do not decompose. These are called non-biodegradable material.
How we manage waste affect our environment and environment in turn affects us. The waste we create has to be carefully managed so that it does not harm our environment and our health. Practicing of three R’s will help us to keep our surrounding clean and healthy.
This means to use less. Use of water and power wisely - We can save electricity by not using it unnecessarily and can save water by closing water tap when it is not in use.
This means using things again.
Examples:
Many materials such as paper, glass, aluminum, plastic etc. can be recycled to make useful things out of them. Recycling means treating or processing material in certain way, so that it can be used again.
